That’s especially the case for bleached hair, as Zoe Kravitz knows. The rockstar spawn and actress on HBO’s Big Little Lies recently dyed her black mane a white-hot blonde, which seems to be trending nowadays (just look at Allison Williams and Cara Delevigne).

Though the new ‘do certainly isn’t done in a natural way—it’s called bleached for a reason—Kravitz has proven that you can still care for dramatically lightened look while staying on the non-toxic side of things.

What’s the actress/musician/general badass using to keep her locks on lock? Coconut oil (of course), according to Vogue.

“My hair breaks really easily, and I think I leave a trail of blonde hair everywhere I go right now,” Kravitz says. But she has found that the MVP of natural beauty has helped her care for her tresses, which have certainly gone through a lot in terms of her dye job.

It’s something other stars have been hip to, as well—Eva Mendes, Nicole Richie, and Priyanka Chopra all use the tropical oil for lust-worthy, healthy hair. Hey, sometimes the best answer is the simplest one.
